CHANGE-MAKING MACHINE.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed March 8, 1917. Serial No. 153,524.

T0 all whom t may concern:

Be it known thaty I, EDWARD C. SIQUEIRA, a citizen of the United States, residing at Oakland, in the countyof Alameda and State of California, have invented certain new and useful Improvements in Change- Making Machines, of which the following is a specification. 4

This invention relatesv to improvements in coin collecting and dispensing handling apparatus and more particularly to a device for making change. The present application is an improvement of my copending application Serial Number 43,051, filed Aug. 2, 1915.

The principal object is to provide efficient mechanism which by the mere movement of a suitable lever, a plurality of coins will be ejected which are equal in value to a coin of larger denomination.

Another object of the invention is to arrange the coin holding tubes, that the coins from the registering mechanism fall directly into these tubes from the inside of the housing, and yet the tubes are open at the top to permit other coins being placed therein from the outside.

With these and other objects in view the invention consists of certain novel features of construction, combination and arrangements of parts herein illustrated and more specifically pointed out in the appended claims.

.To more fully comprehend the invention reference should be had to the drawings forming a part `of the specification and wherein Figure 1 is a view in perspective of the device as viewed from the front.

Fig. 2 is a view in perspective as viewed from the rear.

Fig. 3 is a view in front elevation with the cover plates removed.

Fig. 4 is a sectional plan view on the line 4-4 in Fig. 3.

Fig. 5 is a view in section on the line 5--5 Fig. 4. l

Fig. 6 is a view in plan of the ejecting mechanism below' the coin tubes.

Referring to corresponding parts in the several views by the same'numerals of reference: 1 denotes a base from the sides of which rise a housing consisting of the side plates 2, the front plate 3, and a top 4. About midway up the front of the lwusng e shelf 5 is formed by the plate 6 which contains openings 8 through which coins may be deposited by hand. Surmounting the top of the housing is a coin receptacle 9 into which the coins are deposited and from which they pass to the registering and assorting mechanism denoted in general by 12. As this mechanism forms no part of my present invention and is fully described in my copending application Serial #153,525, filed Mar. 8, 1917, I have not deemed it necessary to describe the same in detail. It is suiiicient to say that as the coins are registered they drop through certain openings in the plate 13, onto the chute 14C or 15 according to value. These chutes are mounted on the rod 16 and they may be shifted laterally, the upper ends being of sufficient width to remain under openings heretofore mentioned, while the lower ends are brought adjacent the coin receiving tubes hereinafter described.

In the machine illustrated, the coin tubes just mentioned are siX in number and while I have assigned certain values to the coins which are contained in the various tubes it will be understood that other values and arrangements of tubes may be used. As herein illustrated the tubes on the left of the machine as viewed in Fig. 3 and denoted by 18 are both of the same size and adapted to receive five-cent pieces. The next two tubes denoted by 19 are for dimes, while the fifth and sixth tubes from the left denoted by 20 and 21 respectively are for twentyfive cent and fifty cent pieces respectively.

The ends of these tubes are attached to the upper and lower plates 22 and 23 respectively and it will be noted that the upper plate is positioned a suiiicient distance below plate 6 to allow the coins which fall down the chutes to slide over this plate into the coin tubes. Below the plate 23 is a plate 24: having certain recesses 25 arranged transversely of the plate and the depth of which are that of the respective coins for which they are adapted. These recesses are equal in number to the coin tubes, are positioned directly under the same and have a width slightly greater than the diameter of the openings in these tubes.

From the front edge of plate 24 extend certain slots 26 to a point approximately under the center of the largest coin tubes and it will be .noted- .ttat the fear peints of the tubes are in alinement. Longitudinally disposed under the plate is a vertical supporting member 27 and in plate 24 back of this supporting member are provided openings 28 that are slightly larger than the respective openings of the tubes associated therewith. It will also be noted that the rear position of these openings 28 are in alinement.

Slidably mounted in the recesses 25 are certain plates 30 which have openings 31 the exact size of the coin tubes positioned thereabove and these openings are adapted to be positioned directly under the opening of the coin tubes when the plates are in their forward position. It will be noted that the openings in the plates 30 and those in the plate 24 intersect more or less, the amount of intersection of the larger opening being greater than those having smaller openings so that the same amount ot movement will cause any of the various openings in plate 30, to coincide with the corresponding opening 28 in `plate 24. The sliding plates 31 have formed on the underside certain arms 35 which project downwardly through the slots 26 heretofore mentionee and contacting with these arms and tending to urge the same forward are springs 36.

Mounted in the side plates 37 is a shaft 38 on which is pivotally mounted certain operating bell crank levers 39. The longer ends 37 of these levers extend through vertical slots in the front plate 3 and are there provided with suitable buttons 40, containing numbers to designate the amount of change which the pressing of that lever will eject. Between the lower ends of side ,plates 37 is a shaft 41 on which is pivotally mounted a number of U-shaped operating members 41, 42, 43 and 44. The shorter arms 45 ofthe bell crank extend vdownwardly and have mounted in their endsrollers 46, which rollers are adapted to contact with the front faces of the various members 41 to 44 inelusive.

It will be noted that member 44 contains a lug 47 which overlaps member 43, and 43 in .turn is provided with a lug 48 which overlaps member 42. Thus when the end righthand member 44 is operated, the members 43 `and y42 will also be moved.

It will be noted that bell cranks, the buttons of which are marked 10, 25, v50 and 100 have their shorter arms contacting with the U-members 41, 42, 43 and 44 respectively. The upper ends of the members 41 to 44 are arranged to contact with the various arms 35. Member 41 it will be seen contacts with the arms 35 on both of the plates associated with tubes 18. The member 42 makes coa tact with the arms of the sliding plates 30 associated with tubes 19 and also with the arm associated with the tube 18 adjacent the tubes 19. Members 43 and 44 contact ythe coins may be easily taken.

In order to accurately position these various plates and consequently the openings in the slides with respect to the openings in the tubes I provide adjusting screws 53 and 54, the former being used to adjust the plates 42, 43, and 44 while the latter is used to adjust plate 41.

Having thus described the various parts of my invention, the manner in which it is operated is as follows:

If ten cents is received and it is desired to give the patron two five-cent pieces in return, the dime is deposited in one of the coin tubes 19 and the bell crank marked 10 is depressed. This rotates member 41, the upper edge of which contacts with the depending arms 35 on the sliding plates 30 under tubes 18. Now if the openings in these sliding plates are of just the size and thickness of a coin it follows that it there is a supply of coins in the various tubes that the lowermost ones will rest within these openings. Hence when the bell crank is depressed these plates will move rearwardly and the coins which are in the openings 31 will be moved over the openings 28, through which they will fall onto the chute 50, and slide by gravity into the receptacle 52.

In a like manner if change for twentyve cents is required, the correspondingly numbered bell crank is depressed. which will operate the sliding plates 30 under the two tubes 19 and the adjacent plate under one of the tubes 18, and thus be ejecting two dimes and one nickel. It a dollars worth of change is to be ejected the correspondingly marked lever is depressed which moves the member 44 and through the lug 47 the member 43, which in turn through the lug 48 attached thereto moves the member 42. The movement of these various members move the plates 30 associated therewith, and there is ejected a coin from one of the tubes 18, from the two tubes 19 and from tubes 20 and 21. As here illustrated fifty cents, twentyiiVe cents, two dimes and a nickel making one dollar in change.

The coins as they are ejected fall onto the chute 50 and slide down into the receptacle 52 placed on the opposite side of the device, within easy reach of the patron.

IWhile I have shown the preferred embodiment of my invention it will be understood that changes in minor features of design and details of construction within the scope of the claims may be resorted t0 e thereof.
